There are many ways to skin a cat. :-)
Do what is easiest for your purposes. I just proposed
one way of placing a point-scaled text at a position
on an existing image.

Maybe you feel more comfortable with your proposed
method. As usual with Perl, there is no "right way", unless
you are getting into some kind of mass production and
efficiencies become important. But for 50 Boy Scout badges,
or a convention of 500 people, efficiency isn't going to matter.
Do what is easiest for you to understand, and the materials
you have to work with.

You really didn't say how you are making the badges,
like is there a limited defined bounding box that each
name must fit in?  Or can you adjust the name-box size
to accomodate longer names? etc. etc.
